How to access SOAP web services using C# with WCF

The following code will connect to Spira, authenticate, connect to a project and then get a list of incidents fixed in a specific release:

   //Instantiate the web-service proxy class and set the URL from the .config file
   spiraImportExport = new TestSuite.SpiraImportExport30.ImportExportClient();
   spiraImportExport.Endpoint.Address = new EndpointAddress("http://servername/SpiraTest/Services/v3_0/ImportExport.svc");

   //Configure the HTTP Binding to handle session cookies
   BasicHttpBinding httpBinding = (BasicHttpBinding)spiraImportExport.Endpoint.Binding;
   httpBinding.AllowCookies = true;
   httpBinding.Security.Mode = BasicHttpSecurityMode.Tls12;

   //Next lets authenticate and connect to the project
   int projectId = 1;
   spiraImportExport.Connection_Authenticate("username", "password");
   spiraImportExport.Connection_ConnectToProject(projectId);

   //Now lets get a list of incidents fixed in Release RL00005
   int releaseId = 5;
   List<RemoteFilter> remoteFilters = new List<RemoteFilter>();
   RemoteFilter remoteFilter = new RemoteFilter();
   remoteFilter.PropertyName = "ResolvedReleaseId";
   remoteFilter.IntValue = releaseId;
   remoteFilters.Add(remoteFilter);
   RemoteSort remoteSort = new RemoteSort();
   remoteSort.PropertyName = "Name";
   remoteSort.SortAscending = true;
   List<RemoteIncident> remoteIncidents = spiraImportExport.Incident_Retrieve(remoteFilters.ToArray(), remoteSort, 1, 999999);

   //Loop through and display ID, name and description
   foreach (RemoteIncident remoteIncident in remoteIncidents)
   {
       Response.Write(remoteIncident.IncidentId);
       Response.Write(remoteIncident.Name);
       Response.Write(remoteIncident.Description);
   }
